The all-new 2022 Yamaha 115HP – 20″ Shaft is Yamaha’s fastest 115-hp four stroke, with a top speed of nearly 51 mph. In addition to top speed, it features tech that is unheard of in other brands. Including a long-track intake system, free-flow exhaust and knock sensor. Furthermore, Its lightweight design combined with 1.8-litre displacement. This makes the V MAX SHO the class leader in torque and top speed. In Addition to that the option of a 20-inch shaft is an exciting new prospect. Finally, it supports mechanical, remote or tiller control.
POWER AND EFFICIENCY – Precision Multi-Point Electronic Fuel Injection delivers the exact amount of fuel needed for optimum performance and efficiency. Yamaha’s EFI optimizes fuel atomization further enhancing fuel economy.
Power and Performance.
- Quiet Power and Performance: Yamaha 115HP – 20″ Shaft design maximizes combustion efficiency in a way that no two stroke can, delivering clean, quiet power and performance.
- Fuel Efficient: Yamaha 115HP – 20″ Shaft designs are up to 40% more fuel efficient than traditional carbureted two strokes.
- Optimum Power: Precision Multi-Point Electronic Fuel Injection and long-track intake system combine to maximize power and fuel efficiency across the line of In-Line Four V MAX SHO® outboards.
- Power Management: An array of advanced sensors constantly provide vital atmospheric and engine conditions to the Engine Control Module (ECM), which instantly makes the precise adjustments for optimum performance.
Reliability and Durability
- Better Lubrication: Wet sump pump lubrication that uses a pressurized oil delivery system through an oil pump.
- Engine Warning System: This system protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, water-in-fuel detection, start-in-gear protection and shift-in prevention at open throttle.
- Corrosion Protection: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ electro-deposited, anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha I-4 V MAX SHO® four-stroke engines.
Convenience and Control
- Extra Space: A four stroke in-line design means there’s no need for an external oil tank. That means less weight and more storage room in the boat for tackle and gear.
- Easy Rigging: Yamaha 115HP – 20″ Shaft outboards feature mechanical controls for easy, convenient rigging with most bass, bay and flats boats, and are compatible with analog, 6Y5 digital or Command Link® gauges.
